WEATHER CHANNEL: Toxic Lake: The Untold Story of Lake Okeechobee

CLEWISTON, Fla. – For months during 2016, plumes of toxic algae turned South Florida’s emerald waters the color of coffee and smothered its inlets under a fetid blanket of guacamole-green goop that killed off fish, suffocated oyster beds and triggered a ferocious outcry from coastal residents.

From NBC’s “Today Show” to The Daily Telegraph of London, news outlets chronicled the closing of beaches, the declaration of a state of emergency and the desperate, heart-breaking efforts of people using garden hoses to save manatees, affectionately known as sea cows, caked in toxic slime and struggling to breathe.

But the reports didn’t explain the most tragic part of the story – that this calamity is man-made. It’s the culmination of 135 years of engineering missteps, hubris and a determination to turn Everglades sawgrass into cash crops. Despite talk of spending $10.5 billion over the next two decades to fix the problem, a cloud of political uncertainty leaves it unclear when, how – or even if – the harmful algae blooms will be stopped.
